Definitions :
1.) Vapour pressure - The measure of the tendency of a material to escape into the environment via gas.
2.) Volatile substances - A substance that evaporates quickly and has high vapor pressure.
3.) Non - volatile substance - A substance that does not evaporate.
4.) External pressure - This is also known as the boiling point of the liquid.
When a solute is added to a solvent the vapor pressure decreases.
Vapour pressure of a solvent is lowered when we add a non - volatile solute since it does not evaporate.
Vapour pressure is inversely proportional to the boiling point.
In that as the vapour pressure decreases, the boiling point increases.
